I haven't had a chance to mess with the newest version yet as it just came out. I did take a brief peek over in the Boonex Unity Forums and found people were posting about a few problems. You might head over there and look around before upgrading.
Remember...Before upgrading backup all your files and database. So you have something to work with and you can restore if anything does go wrong or if you have problems.
